Vitalii K. Dugaev is a professor at the Department of Physics and Medical Engineering in Rzeszow University of Technology, Poland and has been since 2006. He earned his MS in electrical engineering at Lviv Technical University, Ukraine, PhD, and Doctor of Science in physics in Chernivtsi University, Ukraine. He worked as a research fellow for nearly 30 years in the Institute of Materials Science, National Academy of Sciences of Ukraine; Technical University of Lisbon, Portugal; Max Planck Institute for Microstructure Physics, Germany; and Néel Institute, France; and also spent one year as a visiting scientist at the Landau Institute for Theoretical Physics, Russia. He has taught Physics I and II and Solid-State Physics at both undergraduate and graduate levels. His main scientific interests are mostly related to the electronic structure of semiconductors and low-dimensional structures, in addition to the transport properties of semiconductors and spin-resolved transport. Vladimir I. Litvinov is a principal scientist at the Sierra Nevada Corporation, Irvine, California, and has been since 1999. He earned his PhD and Doctor of Science in physics from Chernivtsi National University, Ukraine and Institute of Physics Estonian Academy of Sciences (now the Institute of Physics, University of Tartu, Estonia), respectively. From 1978–1995, he was a member and subsequently the head of the theoretical lab at the Institute of Material Science, National Academy of Science of Ukraine. From 1996–1999, he was a senior research associate at the Center of Quantum Devices at Northwestern University, Evanston, Illinois. His research interests include solid-state and semiconductor physics, semiconductor spintronics, topological insulators, optoelectronic devices, and millimeter-wave scanning antennas.
